METALLIC REINFORCING STRUCTURE FOR CEMENTITIOUS BODIES.

To all whom it may concern:

Be it known that I, EDWARD F. CRANE, citizen of the United States, and resident of Newark, in the county of Essex and State of s In the accompanying drawings, which illustrate the invention, Figure .1 is a transverse sectional view of a c ementitious body I provided with my improved re-ii1forcing structure. Fig. 2 is a detail plan view of the I re-inforcing structure on the line 22, Fig. 1. Fig. 3 is a view showing the manner of assembling the parts of the re-inforcing structure. Fig. 4 is a plan view of a locking plate forming part of the structure. Fig. 5 is a view of a modification of the invention, and Fig. 6 is an elevation of the embodil m'ent of the invention shown in, Fig. 5.

The invention includes, generally, a main re-inforcing bar, a plurality of transversely disposed shearing members or stirrups asso ciated with said bar, and a locking-clip associated with each shearing member forsecuring the same to the bar.

The invention is particularly adapted for use with beams or like bodies constructed of cem'entitious material and is shown. in thisl connection in the illustrated embodiment l thereof. The beam illustrated is of recl tangular shape in'cross section and is desigl nated The main re intorcing bar is designated 3 l and is adapted to extend lengthwise of the beam 2 near the bottom oi the same. The re-ini'orcing bar herein illustrated is ol novel construction, the same being provided with a plu ality of peripheral spirally arranged ribs 3, and the shearing members associated 1 with the bar combine with this particular construction of bar in a peculiar manner to i be hereinafter referred to, which gives additional advantages over a re-inforcingbar; iaving a plane periphery, but it will be l Specification of Letters Patent. Application filed July 19. 190$- Serial No. 326.820.

Patented Feb. 18, 1908.

understood thatthe invention not limited 0 a construction in which this particular shape of bar constitutes one of the parts. One of the shearing members associatedwith the bar is designated 4. It will be understood that a number otthese members are spaced short distances apart throughout the length of the bar 3, are disposed transversel of the same, and are provided with upwardly extending diverging arms 1, 4, projecting toward the upper corners of the beam 2 with their intermediate portions passing beneath the bar 3.

A locking clip 5 is associated with each shearing member. for holding the same to the bar 3. As illustrated herein, the clip consists of a sheet metal plate having a slot 6 in the intermediate portion of the same to allow the arms of the shearing members to pass therethrough, and which slot may, if so desired, be subdivided by crossbar s 7 to pre-,

sent additional interlocking abutments.

In the embodiment of the invention shown in Figs. 1 and 2, the arms of the shearing member are twisted; the lower portions thereof bearing against the adjacent edges of the slot 6 and the cross-bars 7 to thereby prevent relative movement of the shearing member and clip, and the additional twists or spirals acting to prevent movement of the shearing i'nember in the cementitious body. In lieu of the twists in the shearing member for locking the same and clip against relative movei'nent, the arms of said member may be bent as indicated in Fig. 5 to provide abutments 8 which co-act with .the walls of the slot 6 of the clip. {3'

In assembling the parts of the re-inforcing structure, the shearing member is first passed beneath the bar 3, and then the clip 5, while in a [lat condition, is passed down over the anus of said member as indicated in Fig. 3; The clip is then bent around the I rod by means of a hammer or other suitable tool, after which the arms of the member 4 are preferably either twisted as shown in Figs. 1 and 2, or bent as shown in Fig. 5, to interlock with the clip. This method. of assembling the parts is such as to permit 01 the assemblingoperation being readily and conveniently e'll'ected at the place of use, as at a building under construction, which [act is most important in that it facilitates the shipping and handling of the dill'erent parts.

When the cementitious material is molded about the re inforcing structure thus formed, said material enters the slot in the upper part of the clip and becomes keyed between the opposing walls of the'same and the ing member partially embracing said bar and projecting laterally therefrom, and a locking clip passing about the bar to embrace the same from opposite sides thereof with the banembracing-portion of'the shearing member held therebctween and having an o pen-' ing through which the shearing member ex- .tends. 4

2. A re-inforcing structure for cementitious bodies comprising a generally round main bar, a shearing member partially embracing said bar and projecting laterally therefrom, and a locking clip passing about the bar to embracethe same from opposite sides thereof with the bar-embracing portion of the shearing member held therebetween and having an opening through which the shearing member extends.

3. A re-inforcing structure for cementi tious bodies comprising a main bar, a shearing member partially embracing said bar and projecting laterally therefrom, and a locking clip passing about the bar to embrace the same from opposite sides thereof with the bar-e1nl)racing-portion of the shearing member held therebetween.and having an opening through which the shearing member extends; said clip and shearing member having engaging abutments for locking the same against relative movement.

4. A rc-inforcing structure for cementitious bodies comprising a main bar, a shearing member projecting laterally from said bar, and a 100 mg clip securing said member to the bar; said bar having a transverse pro jection which cooperates with the .clip to form a locking recess for interposed cementitious material to lock the clip against movement longitudinally of the bar.

5. A re-inforcing structure for cementitious bodies comprising a main bar having :1 ribbed surface, a shearing member project- ,i ng laterally from said bar, and a locking elip securing said member to the bar and having an opening therein opposite the ribbed sur face of the bar; the walls of said opening and the adjacent surfaces of the bar-providing opposing walls for coi'iperation with interposed cementitious material to lock the clip and associated shearing member against movement lengthwise of the ban.

6. A re-inforcing structure, for .cementi tious bodies comprising a main bar, a shear: ing member having arms, projecting laterally from said. bar, and" a locking clip securing said member to the bar and having an opening through which the arms of the-shearingmember extend, the said opening beingextended centrally between thearms of the v shearing member and in a position opposite the bar to receive cementitlous material therein, for the purpose set forth.
